Abstract

The water nozzle of cock is integrated with the handle. The handle is arranged with a water nozzle at the root of handle. The output direction of water nozzle is toward to the handle, while the handle is connected with the valve base via the valve. The handle can be rotated to switch the valve. When the valve is opened, the water of water nozzle can wash the handle. The invention can on time clean the handle of cock.

Description

Handle self-cleaning water tap

Technical field

The invention belongs to daily necessities, be specially a kind of water tap.

Technical background

The switch knob of existing water tap does not possess automatic cleaning function, often speckles with many bacteriums above, causes user's cross infection each other, particularly some public arenas just all the more so easily, is unfavorable for the prevention and control of infectious diseases.

Summary of the invention

The water tap that the object of the present invention is to provide a kind of handle to clean automatically can in time wash the water that is sprayed when at every turn fetching boiling water tap to handle, thereby helps overcoming the deficiency of existing water tap.

Technological scheme of the present invention is: the handle of water tap is provided with water nozzle, water nozzle can be positioned at the root of handle, and the water outlet direction of water nozzle is towards handle, and handle is connected with valve seat by valve, pulling handle can the open and close valve, and the water that water nozzle flows out when valve open can wash handle.This programme can make the handle of water tap in time be cleaned, and keeps the handle cleaning, reduces the disease propagation that causes therefrom.

Second scheme of the present invention is: based on the first string, the top of handle is provided with water nozzle, and handle can upwards be pulled, and when handle up the time, the water nozzle on handle top can upwards be sprayed water.Activities such as this programme can conveniently wash one's face, washes hair, brushes teeth and gargle because it is more convenient to wash one's face, can be effectively shortened the time of washing one's face, thereby can save a large amount of waters that washes one's face.

Embodiment

The invention will be further described below in conjunction with accompanying drawing:

Embodiment: handle (2) is installed on the valve seat (1), and the root of handle is provided with root water nozzle (3), about each symmetric arrangement, in order to the surface of flushing handle, see Fig. 1, the top of handle is provided with top water nozzle (4).Two of handle the side is installed and is provided with top water intake (5) and root water intake (6), each water intake is connected with corresponding water nozzle respectively by water channel (7), sees Fig. 2.Water channel can form by the mode of casting.Be pressed with water-outlet quantity modulating valve (8) on the water nozzle of top, see Fig. 4.Needle-valve (9) is housed in the modulating valve, and its top is taper, and the bottom is a rib groove structure, cross-sectional Fig. 3 that meets personally of bottom, and rib is provided with screw thread, and needle-valve utilizes this screw thread rotation to be installed on the inwall of modulating valve; The grooved position is a water outlet.Can change gap between face of needle seating and the modulating valve water outlet by the rotation needle-valve, play the effect that adjusts the water yield and water-column.The root water nozzle also can be provided with similar water-outlet quantity modulating valve.

In handle and the valve seat valve assembly is housed, it is positioned at the junction of the two, and handle (2) is connected by valve body (12) with valve seat (1), it is that axle rotates that handle can rely on valve body, see Fig. 5, be provided with nonmetal lubricating sleeve (10), to avoid the phase mutual friction between the metal at corresponding rotary part.Fixedly valve block (19) and rotary valve plate (24) are housed in the valve body, and the two is installed in the valve body by valve casing (23).Valve casing combines by the mode of tenon with groove (22) with valve body.Be provided with sealing gasket 1 (26) between rotary valve plate and the handle, fixedly be provided with sealing gasket 2 (18) between valve block and the valve body.Rotary valve plate, valve casing and handle all have position structure each other, as projection and groove, to avoid rotation and dislocation each other; Equally, fixedly valve block, valve body and valve seat also all have corresponding position structure each other.When handle rotated, can rotating fixedly together by valve casing driven rotary valve block, valve block then keeps motionless.Fixedly valve block is provided with osculum (13), and rotary valve plate is provided with water inlet, top (25) and root water inlet (27), and valve is then opened when aiming at into and out of the water hole, then closes when staggering, thereby plays the effect of open and close valve.

Installing ring (21) is fitted in the valve seat (1) in friction tight mode, and valve body (12) utilizes fore-set (14) roof pressure on installing ring, and the other end of fore-set combines with valve seat in the mode of screw thread.Be provided with seal ring (20) between the inboard of installing ring and the valve body.

The outside of installing ring is provided with limited step (28), sees Fig. 6, and the notch position between two limited steps forms a breach, and this breach makes and forms an annular groove between valve seat and the valve body.The installation side of handle is provided with spring pin (11), this spring pin inserts also can be along with the rotation of handle is slided in annular groove in the above-mentioned annular groove, when spring pin is run into limited step, just define the rotation of handle, thereby the rotation of handle is played position-limiting action.At this moment, valve is in open mode.

But open and close state for perception valve when the handle with sleeve, the breach surface of installing ring is rugged wavy surface (29), on this wavy surface, when handle rotated, spring pin (11) slided on wavy surface spring pin at roof pressure under the effect of spring, spring is compressed and stretch variation, thereby produce different rotational resistances, big as the corner internal resistance at valve open, the corner internal resistance of closing is little, open and close feel is preferably arranged, so that operation when making handle with sleeve.

When handle is in down position, have only root water inlet (27) to be communicated with osculum (13), see Fig. 5, two root water nozzles water outlet about handle; When handle is in up position, have only water inlet, top (25) to be communicated with the water nozzle water outlet of handle top with osculum (13); When handle is positioned at nearly horizontal position, valve closing, all not water outlets of water nozzle.Also can be designed to when handle all water nozzles structure of water outlet all down the time.At this moment, two osculums are arranged on the valve block fixedly, be communicated with two water inlets on the rotary valve plate respectively.And up the time, have only an osculum to be communicated with the water inlet, top at handle, have only top water nozzle water outlet, and the not water outlet of root water nozzle.

The handle both sides are identical with the mounting type and the structure of valve seat, and the hot water or cold water can be by the separately supply of valve of handle both sides.In order to adjust coolant-temperature gage, the handle both sides are the osculum (13) on the valve block fixedly, and the certain included angle that can stagger mutually is so that when handle rotates, the aperture of both sides osculum plays the effect of regulating hot water or cold water's flow and water temperature respectively to large and small opposite changing inversely.

The assembling method of water tap and step are: in the installation room (17) of the valve seat of earlier valve assembly being packed into, go up cover upper sealing ring (20) and lubricating sleeve (10) at valve body (12) then, installing ring (21) is fitted on the valve body (1); The corresponding site spring pin (11) of packing on handle, again handle is alignd with the installation position of valve seat, spring pin is aimed at its annular groove, screw in fore-set (14) by mounting hole (16), according to the requirement of installing and locating, valve assembly is headed into the corresponding site of handle and the chimb of valve body (12) is pressed on the installing ring (21).Get final product with decorating the stifled mounting hole of blocking cap (15) plug at last.The installation method of handle both sides is identical.
